Hello!
We are planning to have a house built and are currently still in the initial planning phase. However, after a conversation with the architect, we are already considering heating options.
We are not building a KfW-certified house, but one strictly following the Energy Saving Ordinance. It will have about 220m² (2,368 sq ft) of living space plus a basement.
In various building specifications from contractors (we are having a turnkey build), we often see heat pumps that require an additional outdoor unit beside the system in the utility room. For aesthetic reasons, we are not very keen on that.
What alternatives are there for this kind of setup?
Gas heating combined with solar (the gas connection is available)?
Geothermal heat pumps?
Or other air-to-water heat pumps that do not require an outdoor unit?
We will probably have a hipped roof (with regard to solar panels). With a flat roof, the panels look quite unattractive.

The daughter is doing her homework in her room (21°C (70°F)) and wants to go to sleep directly afterwards... then she needs 17°C (63°F)... This is not achievable with underfloor heating! It is too slow to react!Even if the radiator is turned off, the children's room probably won't have reached 17°C (63°F) by the next morning, even in winter.

Complete nonsense. In my opinion, a radiator belongs in a child’s room, not underfloor heating!
Example:
The daughter is doing homework in her room (21°C (70°F)) and then wants to go straight to sleep... then she needs 17°C (63°F)... This is not achievable with underfloor heating! It is too slow to respond! In our bedrooms, the temperature is always at least 21°C (70°F).
Not everyone likes to sleep at such low temperatures.
With modern building envelopes, you will never cool a room down by 4°C (7°F) within 30 minutes, unless it is below freezing outside and you ventilate the room by fully opening the windows for half an hour.
Even in that scenario, this is not a problem with underfloor heating, because you can simply turn it off much earlier. The room hardly loses any heat, even without heating.

We don’t even reach 17 degrees here in the middle of winter when the underfloor heating is completely off. In the bedroom, it’s off all year round, but the temperature is always above 17°.
?This probably has less to do with the underfloor heating!
What do you expect from a heating system? That it switches as quickly as a car’s heater... from zero to full power? Always switching between 17 and 24 degrees, because 17 is too cold and 24 is too warm?
What does the body expect or want? It’s probably not changing temperatures, so the inertia of underfloor heating doesn’t even need to be mentioned—you just have to understand how a heating system works and not keep switching it on and off randomly. Then you can manage fine with one consistent room temperature.
The body does not want fluctuating temperatures.

I have never needed that before. However, I am looking forward to the controlled ventilation system to avoid waking up to stale air. But that might be a personal preference.
Seriously though, if this is important for your well-being, consider an existing property. Radiators or not, you won’t achieve the desired effect. Radiators take up a lot of living and floor space and limit your furniture arrangements. Keep that in mind. With the low supply temperatures, they are also larger than you might be used to.

Sleeping at 17 degrees Celsius (63°F) is nonsense... according to that logic, there shouldn’t be any children in tropical regions or in Spain either.
I also don’t know anyone who would want to replace their underfloor heating after having lived with it, even briefly...
I love our underfloor heating precisely because of its inertia... this way, I always have consistent temperatures throughout the entire house, and the gas bill is actually cheaper than in the rented apartment with radiators...
I have never understood why people feel the need to constantly adjust the temperatures up and down.
